TECHNICAL FIELD

The present invention relates to the determination of the gene sequence, mutations of which cause ataxia-telangiectasia (A-T), designated ATM, and the use of the gene and gene products in detection of carriers of the A-T gene, and preparing native and transgenic organisms in which the gene products encoded by the ATM gene or its homolog in other species are artificially produced, or the expression of the native ATM gene is modified.

BACKGROUND OF THE INVENTION

Ataxia-telangiectasia (A-T) is a progressive genetic disorder affecting the central nervous and immune systems, and involving chromosomal instability, cancer predisposition, radiation sensitivity, and cell cycle abnormalities. Studies of the cellular phenotype of A-T have pointed to a defect in a putative system that processes a specific type of DNA damage and initiates a signal transduction pathway controlling cell cycle progression and repair. For a general review of Ataxia-telangiectasia, reference is hereby made to the review Ataxia-Telangiectasis: Closer to Unraveling the Mystery, Eur. J. Hum. Genet. (Shiloh, 1995) which, along with its cited references, is hereby incorporated by reference as well as to the reviews by Harnden (1994) and Taylor et al (1994).

Despite extensive investigation over the last two decades, A-T has remained a clinical and molecular enigma. A-T is a multi-system disease inherited in an autosomal recessive manner, with an average worldwide frequency of 1:40,000-1:100,000 live births and an estimated carrier frequency of 1% in the American population. Notable concentrations of A-T patients outside the United States are in Turkey, Italy and Israel. Israeli A-T patients are Moroccan Jews, Palestinian Arabs, Bedouins and Druzes.

Cerebellar ataxia that gradually develops into general motor dysfunction is the first clinical hallmark and results from progressive loss of Purkinje cells in the cerebellum. Oculocutaneous telangiectasia (dilation of blood vessels) develops in the bulbar conjunctiva and facial skin, and is later accompanied by graying of the hair and atrophic changes in the skin. The co-occurrence of cerebellar ataxia and telangiectases in the conjunctivae and occasionally on the facial skin—the second early hallmark of the disease—usually establishes the differential diagnosis of A-T from other cerebellar ataxias. Somatic growth is retarded in most patients, and ovarian dysgenesis is typical for female patients. Among occasional endocrine abnormalities, insulin-resistant diabetes is predominant, and serum levels of alpha-fetoprotein and carcinoembryonic antigen are elevated. The thymus is either absent or vestigial, and other immunological defects include reduced levels of serum IgA, IgE or IgG2, peripheral lymphopenia, and reduced responses to viral antigens and allogeneic cells, that cause many patients to suffer from recurrent sinopulmonary infections.

Cancer predisposition in A-T is striking: 38% of patients develop malignancies, mainly lymphoreticular neoplasms and leukemias. But, A-T patients manifest acute radiosensitivity and must be treated with reduced radiation doses, and not with radiomimetic chemotherapy. The most common cause of death in A-T, typically during the second or third decade of life, is sinopulmonary infections with or without malignancy.

The complexity of the disease is reflected also in the cellular phenotype. Chromosomal instability is expressed as increased chromosomal breakage and the appearance in lymphocytes of clonal translocations specifically involving the loci of the immune system genes. Such clones may later become predominant when a lymphoreticular malignancy appears. Primary fibroblast lines from A-T patients show accelerated senescence, increased demand for certain growth factors, and defective cytoskeletal structure. Most notable is the abnormal response of A-T cells to ionizing radiation and certain radiomimetic chemicals. While hypersensitive to the cytotoxic and clastogenic effects of these agents, DNA synthesis is inhibited by these agents to a lesser extent than in normal cells. The concomitant lack of radiation-induced cell cycle delay and reduction of radiation-induced elevation of p53 protein are evidence of defective checkpoints at the G1, S and G2 phases of the cell cycle. The G1 and G2 checkpoint defects are evident as reduced delay in cell cycle progression following treatment with ionizing radiation or radiomimetic chemicals, while the rise in the p53 protein level usually associated in normal cells with radiation-induced G1 arrest is delayed in A-T cells. The defective checkpoint at the S phase is readily observed as radioresistant DNA synthesis (RDS). Increased intrachromosomal recombination in A-T cells was also noted recently. Cellular sensitivity to DNA damaging agents and RDS are usually considered an integral part of the A-T phenotype.

Although these clinical and cellular features are considered common to all “classical” A-T patients, variations have been noted. Milder forms of the disease with later onset, slower clinical progression, reduced radiosensitivity and occasional absence of RDS have been described in several ethnic groups (Fiorilli, 1985; Taylor et al., 1987; Ziv et al., 1989; Chessa et al., 1992). Additional phenotypic variability possibly related to A-T is suggested by several disorders that show “partial A-T phenotype” with varying combinations of ataxia, immunodeficiency and chromosomal instability without telangiectases (12-16) (Ying & Decoteau, 1983; Byrne et al., 1984; Aicardi et al., 1988; Maserati et a;., 1988; Friedman & Weitberg, 1993). Still, other disorders display the A-T phenotype and additional features; most notable is the Nijmegen breakage syndrome that combines A-T features with microcephaly, sometimes with mental retardation, but without telangiectases (Weemaes et al., 1994).

Prenatal diagnoses of A-T using cytogenetic analysis or measurements of DNA synthesis have been reported, but these tests are laborious and subject to background fluctuations and, therefore, not widely used.

A-T homozygotes have two defective copies of the A-T gene and are affected with the disease. A-T heterozygotes (carriers) have one normal copy of the gene and one defective copy of the gene and are generally healthy. When two carriers have children, there is a 25% risk in every pregnancy of giving birth to an A-T affected child.

A-T heterozygotes show a significant excess of various malignancies, with a 3- to 4-fold increased risk for all cancers between the ages of 20 and 80, and a 5-fold increased risk of breast cancer in women. These observations turn A-T into a public health problem and add an important dimension to A-T research, particularly to heterozygote identification. Cultured cells from A-T heterozygotes indeed show an intermediate degree of X-ray sensitivity, but the difference from normal cells is not always large enough to warrant using this criterion as a laboratory assay for carrier detection. The main reason for the unreliability of this assay is the various degrees of overlap between A-T heterozygotes and non-heterozygotes with respect to radiosensitivity. Cytogenetic assays for carriers have the same problems as for prenatal diagnosis, they are labor intensive and not always consistent.

The nature of the protein missing in A-T is unknown. Cell fusion studies have established four complementation groups in A-T, designated A, C, D and E, suggesting the probable involvement of at least four genes or four types of mutations in one gene, with inter-allelic complementation. These four groups are clinically indistinguishable and were found to account for 55%, 28%, 14% and 3% of some 80 patients typed to date. In Israel, several Moroccan Jewish patients were assigned to group C, while Palestinian Arab patients were assigned to group A.

The general chromosomal localization of the putative A-T gene(s) has been determined, but not the sequence. An A-T locus containing the A-T(A) mutations was localized by Gatti et al. (1988) to chromosome 11, region q22-23, using linkage analysis. The A-T(C) locus was localized by applicant to the same region of chromosome 11, region q22-23, by linkage analysis of an extended Jewish Moroccan A-T family (Ziv et al., 1991). Further studies, conducted by an international consortium in which applicant participated (McConville et al., 1990; Foroud et al., 1991; Ziv et al., 1992), reconfirmed this localization in a series of studies and gradually narrowed the A-T locus to an interval estimated at 4 centimorgan, which probably contains also the A-T(E) mutations.

A proposed gene for complementation group D is disclosed in U.S. Pat. No. 5,395,767 to Murnane et al., issued Mar. 7, 1995. This sequence was found not to be mutated in any complementation group of A-T. Further, the gene sequence was mapped physically distant from the presumptive A-T locus.

Therefore, in order to better understand the nature and effects of A-T, as well as to more accurately and consistently determine those individuals who may carry the defective gene for A-T, it would be advantageous to isolate and determine the gene sequence, mutations of which are responsible for causing A-T, and utilize this sequence as a basis for detecting carriers of A-T and thereby be able to more beneficially manage the underlying conditions and predispositions of those carriers of the defective gene.

SUMMARY OF THE INVENTION AND ADVANTAGES

According to the present invention, a gene designated ATM and mutations of this gene which cause ataxia-telangiectasia (A-T), has been purified, isolated and determined as well as mutations of the gene.

The present invention further includes the method for identifying carriers of the defective A-T gene in a population and defective A-T gene products.

Further, the present invention provides transgenic and knockout nonhuman animal and cellular models.

The role of the ATM gene in cancer predisposition makes this gene an important target for screening. The detection of A-T mutation carriers is particularly significant in light of their radiation-sensitivity so that carrier exposure to radiation can be properly monitored and avoided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The present invention consists of a purified, isolated and cloned nucleic acid sequence encoding a gene, designated ATM, mutations in which cause ataxia-telangiectasia and genetic polymorphisms thereof. The nucleic acid can be genomic DNA, cDNA or mRNA.

The complete coding sequence of the ATM gene is set forth in SEQ ID No:2 and was submitted to the GenBank database under accession number U33841. There is extensive alternate splicing at the 5′ untranslated region (5′UTR) of the ATM transcript giving rise to twelve different 5′ UTRs. The sequence of the longest 5′UTR is set forth in SEQ ID No:9. The first exon in this sequence is designated 1b. There is an alternative leader exon, designated 1a (SEQ ID No:10). The sequence of the complete 3′UTR is set forth in SEQ ID No:8. Together these sequences contain the complete sequence of the ATM transcript.

Polymorphisms are variants in the sequence generally found between different ethnic and geographic locations which, while having a different sequence, produce functionally equivalent gene products.

Current mutation data (as shown in Tables 1 and 2) indicate that A-T is a disease characterized by considerable allelic heterogenicity. Mutations imparting defects into the A-T gene can be point mutations, deletions, insertions or rearrangements. The mutations can be present within the nucleotide sequence of either/or both alleles of the ATM gene such that the resulting amino acid sequence of the ATM protein product is altered in one or both copies of the gene product; when present in both copies imparting ataxia-telangiectasia. Alternatively, a mutation event selected from the group consisting of point mutations, deletions, insertions and rearrangements could have occurred within the flanking sequences and/or regulatory sequences of ATM such that regulation of ATM is altered imparting ataxia-telangiectasia.

Table 1 illustrates several mutations in the ATM gene found in A-T patients. Mutations in the ATM gene were found in all of the complementation groups suggesting that ATM is the sole gene responsible for all A-T cases.

Table 2 illustrates the 44 mutations identified to date in applicant's patient cohort and include 34 new ones and 10 previously listed in Table 1. These mutations were found amongst 55 A-T families: many are unique to a single family, while others are shared by several families, most notably the 4 nt deletion, 7517del4, which is common to 6 A-T families from South-Central Italy. The nature and location of A-T mutations, as set forth in Table 2, provide insight into the function of the ATM protein and the molecular basis of this pleiotropic disease.

This series of 44 A-T mutations is dominated by deletions and insertions. The smaller ones, of less than 12 nt, reflect identical sequence alterations in genomic DNA. Deletions spanning larger segments of the ATM transcript were found to reflect exon skipping, not corresponding genomic deletions. Of the 44 A-T mutations identified, 39 (89%) are expected to inactivate the ATM protein by truncating it, by abolishing correct initiation or termination of translation, or by deleting large segments. Additional mutations are four smaller in-frame deletions and insertions, and one substitution of a highly conserved amino acid at the PI 3-kinase domain. The emerging profile of mutations causing A-T is thus dominated by those expected to completely inactivate the ATM protein. ATM mutations with milder effects appear to result in phenotypes related, but not identical, to A-T. In view of the pleiotropic nature of the ATM gene, the range of phenotypes associated with various ATM genotypes may be even broader, and include mild progressive conditions not always defined as clear clinical entities as discussed herein below in Example 3. Screening for mutations in this gene in such cases will reveal wider boundaries for the molecular pathology associated with the ATM gene. The present invention therefore allows the identification of these mutations in subjects with related phenotypes to A-T.

The ATM gene leaves a great deal of room for mutations: it encodes a large transcript. The variety of mutations identified in this study indeed indicates a rich mutation repertoire. Despite this wealth of mutations, their structural characteristics point to a definite bias towards those that inactivate or eliminate the ATM protein. The nature or distribution of the genomic deletions among these mutations do not suggest a special preponderance of the ATM gene for such mutations, such as that of the dystrophin (Anderson and Kunkel, 1992) or steroid sulfatase (Ballabio et al., 1989) genes which are particularly prone to such deletions. Thus, one would have expected also a strong representation of missense mutations, which usually constitute a significant portion of the molecular lesions in many disease genes (Cooper and Krawczak, 1993; Sommer, 1995). However, only one such mutation was identified in the present study. Other point mutations reflected in this series are those that probably underlie the exon skipping deletions observed in many patients, again, exerting a severe structural effect on the ATM protein.

In cloning the gene for A-T (Example 2), the strategy used was a standard strategy in identifying a disease gene with an unknown protein product known as positional cloning, as is well known in the art. In positional cloning, the target gene is localized to a specific chromosomal region by establishing linkage between the disease and random genetic markers defined by DNA polymorphisms. Definition of the smallest search interval for the gene by genetic analysis is followed by long-range genomic cloning and identification of transcribed sequences within the interval. The disease gene is then identified among these sequences, mainly by searching for mutations in patients.

Several important and long sought disease genes were isolated recently in this way (Collins, 1992; Attree et al., 1992; Berger et al., 1992; Chelly et al., 1993; Vetrie et al., 1993; Trofatter et al., 1993; The Huntington's Disease Collaborative Research Group, 1993; The European Polycystic Kidney Disease Consortium, 1994; Miki et al., 1994).

Two complementary methods were used for the identification of transcribed sequences (gene hunting): hybrid selection based on direct hybridization of genomic DNA with cDNAs from various sources (Parimoo et al., 1991; Lovett et al., 1991); and exon trapping (also called exon amplification), which identifies putative exons in genomic DNA by virtue of their splicing capacity (Church et al., 1993). In hybrid selection experiments, cosmid and YAC clones served to capture cross-hybridizing sequences in cDNA collections from placenta, thymus and fetal brain, using the magnetic bead capture protocol (Morgan et al., 1992; Tagle et al., 1993). In parallel experiments, YAC clones were bound to a solid matrix and used to select cDNA fragments from a heterogeneous cDNA collection representing several human tissues (Parimoo et al., 1993). The cosmids were also used for exon trapping with the pSPL3 vector (Church et al., 1994). The captured cDNA fragments and trapped exons were mapped back to the A-T region by hybridization to several radiation hybrids containing various portions of the 11q22-23 region (Richard et al., 1993; James et al., 1994), and to high-density grids containing all the YACs and cosmids spanning this interval. An extensive transcriptional map of the A-T region was thus constructed (Shiloh et al., 1994).

Pools of adjacent cDNA fragments and exons, expected to converge into the same transcriptional units, were used to screen cDNA libraries. A cluster of 5 cDNA fragments and 3 exons mapped in close proximity to the marker D11S535, where the location score for A-T had peaked (Lange et al., 1995). All these sequences hybridized to the same 5.9 kb of the cDNA clone, 7-9, (SEQ ID No:1) obtained from a fibroblast cDNA library.

Hybridization of the 7-9 cDNA clone to the radiation hybrid panel indicated that the entire transcript was derived from the chromosome 11 locus. The full sequence of this clone (SEQ ID No:1) was obtained using a shotgun strategy, and found to contain 5921 bp which includes an open reading frame (ORF) of 5124 nucleotides, a 538 bp 3′ untranslated region (3′ UTR), and a 259 bp 5′ non-coding sequence containing stop codons in all reading frames. (Genbank Accession No. U26455). Two Alu repetitive elements were observed at the 3′ end of this clone and in nine smaller clones representing this gene from the same cDNA library. Since no polyadenylation signal was identified in these cDNA clones, their poly(A) tracts were assumed to be associated with the Alu element rather than being authentic poly(A) tails of these transcripts. This assumption was later supported when applicants identified a cDNA clone derived from the same gene in a leukocyte cDNA library, with an alternative 3′ UTR containing a typical polyadenylation signal. Alignment of the cDNA with the genomic physical map showed that the corresponding gene is transcribed from centromere to telomere.

Hybridization of a probe containing the entire ORF of clone 7-9 to northern blots from various tissues and cell lines revealed a major transcript of 12 kb, later shown to be 13 kb, in all tissues and cell types examined, and minor species of various sizes in several tissues, possibly representing alternatively spliced transcripts of the corresponding gene or other homologous sequences. Genomic sequencing later identified the 5′ non-coding region of clone 7-9 as sequences of the unspliced adjacent intron. Two other cDNA clones from a leukocyte cDNA library were found to contain this intronic sequence in their 5′ ends. These clones may represent splicing intermediates.

The 7-9 cDNA clone represents only part of the ATM gene transcript. Successive screening of randomly-primed cDNA libraries identified a series of partly overlapping cDNA clones and enabled the construction of a cDNA contig of about 10 Kb (FIG. 2). The gene coding for this transcript spans about 150 Kb of genomic DNA.

The composite cDNA of 9860 bp (GenBank Accession No. U33841; SEQ ID No:2) includes an open reading frame of 9168 nucleotides, a 538 bp 3′ untranslated region (UTR), and a 164 bp 5′ UTR containing stop codons in all reading frames. The sequence surrounding the first in-frame initiation codon (ACCATGA) resembles the consensus sequence proposed by Kozak for optimal initiation of translation, (A/G)CCATGG (ref. 20 in Savitsky et al, 1995b). No polyadenylation signal was found at the 3′ UTR. The same poly(A) tail was found in all cDNA clones and 3′ RACE products isolated to date in applicant's laboratory, however, this poly(A) tail most likely belongs to the Alu element contained in the 3′ UTR.

Sequencing and PCR analysis of 32 partial ATM cDNA clones, obtained from 11 cDNA libraries representing 8 different tissues, did not show coding sequences in addition to those presented herein.

The invention further provides a purified protein as encoded by the ATM gene (SEQ ID No:2) and analogs thereof. A consensus complete sequence is set forth in SEQ ID No:3. The present invention further provides for mutations in SEQ ID No:2 and SEQ ID No:3 which cause ataxia-telangiectasia, for example, as set forth in Tables 1 and 2.

This product (SEQ ID No:3) of the ATM Open Reading Frame (SEQ ID No:2) is a large protein of 3056 amino acids, with an expected molecular weight of 350.6 kDa. The ATM gene product (SEQ ID No:3) contains a PI-3 kinase signature at codons 2855-2875, and a potential leucine zipper at codons 1217-1238. The presence of this leucine zipper may suggest possible dimerization of the ATM protein or interaction with additional proteins. No nuclear localization signal, transmembrane domains or other motifs were observed in this protein sequence.

The ATM gene product is a member of a family of large proteins that share a highly conserved carboxy-terminal region of about 300 amino acids showing high sequence homology to the catalytic domain of PI-3 kinases. Among these proteins are Tel1p and Mec1p in budding yeast, rad3p in fission yeast, the TOR proteins in yeast and their mammalian counterpart, FRAP (RAFT1), MEI-41 in Drosophila melanogaster, and the catalytic subunit of DNA-dependent protein kinase (DNA-PKcs) in mammals. All of these proteins are implicated in cell cycle control and some of them, like Mec1p, rad3p and DNA-PKcs are involved in response to DNA damage (Table 3). The central core of the PI-3 kinase-like domain contains two subdomains with highly conserved residues present in nearly all kinases, including protein and PI-3 kinases. The residues Asp and Asn (at positions 2870 and 2875 in ATM), and the triplet Asp-Phe-Gly (at positions 2889-2891), which represents the most highly conserved short stretch in the protein kinase catalytic domain, have been implicated in the binding of ATP and phosphotransferase activity. Mutations in the genes encoding these proteins result in a variety of phenotypes that share features with A-T, such as radiosensitivity, chromosomal instability, telomere shortening, and defective cell cycle checkpoints (reviewed by Savitsky et al., 1995a and b; Zakian, 1995).

A possible working model for the ATM protein's function is DNA-PK, a serine/threonine protein kinase that is activated in vitro by DNA double-strand breaks and responds by phosphorylating several regulatory proteins (Gottlieb and Jackson, 1994). The ATM protein may be responsible for conveying a signal evoked by a specific DNA damage to various checkpoint systems, possibly via lipid or protein phosphorylation.

The present invention further includes a recombinant protein encoded by SEQ ID No:3. This recombinant protein is isolated and purified by techniques known to those skilled in the art.

An analog will be generally at least 70% homologous over any portion that is functionally relevant. In more preferred embodiments, the homology will be at least 80% and can approach 95% homology to the ATM protein. The amino acid sequence of an analog may differ from that of the ATM protein when at least one residue is deleted, inserted or substituted but the protein remains functional and does not cause A-T. Differences in glycosylation can provide analogs.

The present invention provides an antibody, either polyclonal or monoclonal, which specifically binds to a polypeptide/protein encoded by the ATM gene and/or mutant epitopes on the protein. Examples of such antibodies are set forth in Example 5. In preparing the antibody, the protein (with and without mutations) encoded by the ATM gene and polymorphisms thereof is used as a source of the immunogen. Peptide amino acid sequences isolated from the amino acid sequence as set forth in SEQ ID No:3 or mutant peptide sequences can also be used as an immunogen.

The antibodies may be either monoclonal or polyclonal. Conveniently, the antibodies may be prepared against a synthetic peptide based on the sequence, or prepared recombinantly by cloning techniques or the natural gene product and/or portions thereof may be isolated and used as the immunogen. Such proteins or peptides can be used to produce antibodies by standard antibody production technology well known to those skilled in the art as described generally in Harlow and Lane, Antibodies: A Laboratory Manual, Cold Spring Harbor Laboratory Press, Cold Spring Harbor, N.Y., 1988.

For producing polyclonal antibodies a host, such as a rabbit or goat, is immunized with the protein or peptide, generally with an adjuvant and, if necessary, coupled to a carrier; antibodies to the protein are collected from the sera.

For producing monoclonal antibodies, the technique involves hyperimmunization of an appropriate donor, generally a mouse, with the protein or peptide fragment and isolation of splenic antibody producing cells. These cells are fused to a cell having immortality, such as a myeloma cell, to provide a fused cell hybrid which has immortality and secretes the required antibody. The cells are then cultured, in bulk, and the monoclonal antibodies harvested from the culture media for use.

The antibody can be bound to a solid support substrate or conjugated with a detectable moiety or be both bound and conjugated as is well known in the art. (For a general discussion of conjugation of fluorescent or enzymatic moieties see Johnstone and Thorpe, Immunochemistry in Practice, Blackwell Scientific Publications, Oxford, 1982.) The binding of antibodies to a solid support substrate is also well known in the art. (see for a general discussion Harlow and Lane Antibodies: A Laboratory Manual, Cold Spring Harbor Laboratory Publications, New York, 1988) The detectable moieties contemplated with the present invention can include, but are not limited to, fluorescent, metallic, enzymatic and radioactive markers such as biotin, gold, ferritin, alkaline phosphatase, β-galactosidase, peroxidase, urease, fluorescein, rhodamine, tritium, ¹⁴C and iodination.

The present invention provides vectors comprising an expression control sequence operatively linked to the nucleic acid sequence of the ATM gene, SEQ ID No:2 and portions thereof as well as mutant sequences which lead to the expression of A-T. The present invention further provides host cells, selected from suitable eucaryotic and procaryotic cells, which are transformed with these vectors.

Using the present invention, it is possible to transform host cells, including E. coli, using the appropriate vectors so that they carry recombinant DNA sequences derived from the ATM transcript or containing the entire ATM transcript in its normal form or a mutated sequence containing point mutations, deletions, insertions, or rearrangements of DNA which lead to the expression of A-T. Such transformed cells allow the study of the function and the regulation of the A-T gene. Use of recombinantly transformed host cells allows for the study of the mechanisms of A-T and, in particular it will allow for the study of gene function interrupted by the mutations in the A-T gene region.

Vectors are known or can be constructed by those skilled in the art and should contain all expression elements necessary to achieve the desired transcription of the sequences. Other beneficial characteristics can also be contained within the vectors such as mechanisms for recovery of the nucleic acids in a different form. Phagemids are a specific example of such beneficial vectors because they can be used either as plasmids or as bacteriophage vectors. Examples of other vectors include viruses such as bacteriophages, baculoviruses and retroviruses, DNA viruses, cosmids, plasmids and other recombination vectors. The vectors can also contain elements for use in either procaryotic or eucaryotic host systems. One of ordinary skill in the art will know which host systems are compatible with a particular vector.

The vectors can be introduced into cells or tissues by any one of a variety of known methods within the art. Such methods can be found generally described in Sambrook et al., Molecular Cloning: A Laboratory Manual, Cold Springs Harbor Laboratory, New York (1992), in Ausubel et al., Current Protocols in Molecular Biology, John Wiley and Sons, Baltimore, Md. (1989), Chang et al., Somatic Gene Therapy, CRC Press, Ann Arbor, Mich. (1995), Vega et al., Gene Targeting, CRC Press, Ann Arbor, Mich. (1995) and Gilboa et al (1986) and include, for example, stable or transient transfection, lipofection, electroporation and infection with recombinant viral vectors. Introduction of nucleic acids by infection offers several advantages over the other listed methods. Higher efficiency can be obtained due to their infectious nature. See also U.S. Pat. Nos. 5,487,992 and 5,464,764. Moreover, viruses are very specialized and typically infect and propagate in specific cell types. Thus, their natural specificity can be used to target the vectors to specific cell types in vivo or within a tissue or mixed culture of cells. Viral vectors can also be modified with specific receptors or ligands to alter target specificity through receptor mediated events.

Recombinant methods known in the art can also be used to achieve the sense, antisense or triplex inhibition of a target nucleic acid. For example, vectors containing antisense nucleic acids can be employed to express protein or antisense message to reduce the expression of the target nucleic acid and therefore its activity.

A specific example of DNA viral vector for introducing and expressing antisense nucleic acids is the adenovirus derived vector Adenop53TK. This vector expresses a herpes virus thymidine kinase (TK) gene for either positive or negative selection and an expression cassette for desired recombinant sequences such as antisense sequences. This vector can be used to infect cells that have an adenovirus receptor which includes most cancers of epithelial origin as well as others. This vector as well as others that exhibit similar desired functions can be used to treat a mixed population of cells include, for example, an in vitro or ex vivo culture of cells, a tissue or a human subject.

Additional features can be added to the vector to ensure its safety and/or enhance its therapeutic efficacy. Such features include, for example, markers that can be used to negatively select against cells infected with the recombinant virus. An example of such a negative selection marker is the TK gene described above that confers sensitivity to the anti-viral gancyclovir. Negative selection is therefore a means by which infection can be controlled because it provides inducible suicide through the addition of antibiotic. Such protection ensures that if, for example, mutations arise that produce altered forms of the viral vector or sequence, cellular transformation will not occur. Features that limit expression to particular cell types can also be included. Such features include, for example, promoter and regulatory elements that are specific for the desired cell type.

Recombinant viral vectors are another example of vectors useful for in vivo expression of a desired nucleic acid because they offer advantages such as lateral infection and targeting specificity. Lateral infection is inherent in the life cycle of, for example, retrovirus and is the process by which a single infected cell produces many progeny virions that bud off and infect neighboring cells. The result is that a large area becomes rapidly infected, most of which was not initially infected by the original viral particles. This is in contrast to vertical-type of infection in which the infectious agent spreads only through daughter progeny. Viral vectors can also be produced that are unable to spread laterally. This characteristic can be useful if the desired purpose is to introduce a specified gene into only a localized number of targeted cells.

As described above, viruses are very specialized infectious agents that have evolved, in many cases, to elude host defense mechanisms. Typically, viruses infect and propagate in specific cell types. The targeting specificity of viral vectors utilizes its natural specificity to specifically target predetermined cell types and thereby introduce a recombinant gene into the infected cell. The vector to be used in the methods of the invention will depend on desired cell type to be targeted. For example, if breast cancer is to be treated, then a vector specific for such epithelial cells should be used. Likewise, if diseases or pathological conditions of the hematopoietic system are to be treated, then a viral vector that is specific for blood cells and their precursors, preferably for the specific type of hematopoietic cell, should be used.

Retroviral vectors can be constructed to function either as infectious particles or to undergo only a single initial round of infection. In the former case, the genome of the virus is modified so that it maintains all the necessary genes, regulatory sequences and packaging signals to synthesize new viral proteins and RNA. Once these molecules are synthesized, the host cell packages the RNA into new viral particles which are capable of undergoing further rounds of infection. The vector's genome is also engineered to encode and express the desired recombinant gene. In the case of non-infectious viral vectors, the vector genome is usually mutated to destroy the viral packaging signal that is required to encapsulate the RNA into viral particles. Without such a signal, any particles that are formed will not contain a genome and therefore cannot proceed through subsequent rounds of infection. The specific type of vector will depend upon the intended application. The actual vectors are also known and readily available within the art or can be constructed by one skilled in the art using well-known methodology.

If viral vectors are used, for example, the procedure can take advantage of their target specificity and consequently, do not have to be administered locally at the diseased site. However, local administration may provide a quicker and more effective treatment, administration can also be performed by, for example, intravenous or subcutaneous injection into the subject. Injection of the viral vectors into a spinal fluid can also be used as a mode of administration, especially in the case of neuro-degenerative diseases. Following injection, the viral vectors will circulate until they recognize host cells with the appropriate target specificity for infection.

Transfection vehicles such as liposomes can also be used to introduce the non-viral vectors described above into recipient cells within the inoculated area. Such transfection vehicles are known by one skilled within the art.

The present invention includes the construction of transgenic and knockout organisms that exhibit the phenotypic manifestations of A-T. The present invention provides for transgenic ATM gene and mutant ATM gene animal and cellular (cell lines) models as well as for knockout ATM models. The transgenic models include those carrying the sequence set forth SEQ ID Nos:2,8,9 (or 10). These models are constructed using standard methods known in the art and as set forth in U.S. Pat. Nos. 5,487,992, 5,464,764, 5,387,742, 5,360,735, 5,347,075, 5,298,422, 5,288,846, 5,221,778, 5,175,385, 5,175,384, 5,175,383, 4,736,866 as well as Burke and Olson, (1991), Capecchi, (1989), Davies et al., (1992), Dickinson et al., (1993), Huxley et al., (1991), Jakobovits et al., (1993), Lamb et al., (1993), Rothstein, (1991), Schedl et al., (1993), Strauss et al., (1993). Further, patent applications WO 94/23049, WO 93/14200, WO 94/06908, WO 94/28123 also provide information. See also in general Hogan et al “Manipulating the Mouse Embryo” Cold Spring Harbor Laboratory Press, 2nd Edition (1994).

Further, the mouse homolog of the A-T gene, designated Atm, has been identified as set forth in detail in Example 4, hereinbelow. The coding sequence of Atm (SEQ ID No:11), the mouse homolog of the human gene ATM defective in A-T, was cloned and found to contain an open reading frame encoding a protein of 3,066 amino acids (SEQ ID No:12) with 84% overall identity and 91% similarity to the human ATM protein (SEQ ID No:3). Variable levels of expression of Atm were observed in different tissues. Fluorescence in situ hybridization and linkage analysis located the Atm gene on mouse chromosome 9, band 9C, in a region homologous to the ATM region on human chromosome 11q22-23. The present invention includes the -construction of mice in which the mouse homolog of the A-T gene has been knocked out.

According to the present invention, there is provided a method for diagnosing and detecting carriers of the defective gene responsible for causing A-T. The present invention further provides methods for detecting normal copies of the ATM gene and its gene product. Carrier detection is especially important since A-T mutations underlie certain cases of cancer predisposition in the general population. Identifying the carriers either by their defective gene or by their missing or defective protein(s) encoded thereby, leads to earlier and more consistent diagnosis of A-T gene carriers. Thus, since carriers of the disease are more likely to be cancer-prone and/or sensitive to therapeutic applications of radiation, better surveillance and treatment protocols can be initiated for them. Conversely, exclusion of A-T heterozygotes from patients undergoing radiotherapy can allow for establishing routinely higher dose schedules for other cancer patients thereby improving the efficacy of their treatment.

Briefly, the methods comprise the steps of obtaining a sample from a test subject, isolating the appropriate test material from the sample and assaying for the target nucleic acid sequence or gene product. The sample can be tissue or bodily fluids from which genetic material and/or proteins are isolated using methods standard in the art. For example, DNA can be isolated from lymphocytes, cells in amniotic fluid and chorionic villi (Llerena et al., 1989).

More specifically, the method of carrier detection is carried out by first obtaining a sample of either cells or bodily fluid from a subject. Convenient methods for obtaining a cellular sample can include collection of either mouth wash fluids or hair roots. A cell sample could be amniotic or placental cells or tissue in the case of a prenatal diagnosis. A crude DNA could be made from the cells (or alternatively proteins isolated) by techniques well known in the art. This isolated target DNA is then used for PCR analysis (or alternatively, Western blot analysis for proteins from a cell line established from the subject) with appropriate primers derived from the gene sequence by techniques well known in the art. The PCR product would then be tested for the presence of appropriate sequence variations in order to assess genotypic A-T status of the subject.

The specimen can be assayed for polypeptides/proteins by immunohistochemical and immunocytochemical staining (see generally Stites and Terr, Basic and Clinical Immunology, Appleton and Lange, 1994), ELISA, RIA, immunoblots, Western blotting, immunoprecipitation, functional assays and protein truncation test. In preferred embodiments, Western blotting, functional assays and protein truncation test (Hogervorst et al., 1995) will be used. mRNA complementary to the target nucleic acid sequence can be assayed by in situ hybridization, Northern blotting and reverse transcriptase-polymerase chain reaction. Nucleic acid sequences can be identified by in situ hybridization, Southern blotting, single strand conformational polymorphism, PCR amplification and DNA-chip analysis using specific primers. (Kawasaki, 1990; Sambrook, 1992; Lichter et al, 1990; Orita et al, 1989; Fodor et al., 1993; Pease et al., 1994)

ELISA assays are well known to those skilled in the art. Both polyclonal and monoclonal antibodies can be used in the assays. Where appropriate other immunoassays, such as radioimmunoassays (RIA) can be used as are known to those in the art. Available immunoassays are extensively described in the patent and scientific literature. See, for example, U.S. Pat. Nos. 3,791,932; 3,839,153; 3,850,752; 3,850,578; 3,853,987; 3,867,517; 3,879,262; 3,901,654; 3,935,074; 3,984,533; 3,996,345; 4,034,074; 4,098,876; 4,879,219; 5,011,771 and 5,281,521 as well as Sambrook et al, 1992.

Current mutation data (as shown in Tables 1 and 2) indicate that A-T is a disease characterized by considerable allelic heterogenicity. It is not surprising that there are hundreds (or even thousands) of ATM mutations (as is the case for cystic fibrosis and BRCAI) as shown in Table 2. Thus, it will be important for a successful mutation screen to be able to detect all possible nucleotide alterations in the ATM gene, rather than being focused on a limited subset. Methods including direct sequencing of PCR amplified DNA or RNA or DNA chip hybridization (Fodor et al., 1993; Pease et al., 1994) can be applied along with other suitable methods known to those skilled in the art.

In order to use the method of the present invention for diagnostic applications, it is advantageous to include a mechanism for identifying the presence or absence of target polynucleotide sequence (or alternatively proteins). In many hybridization based diagnostic or experimental procedures, a label or tag is used to detect or visualize for the presence or absence of a particular polynucleotide sequence. Typically, oligomer probes are labelled with radioisotopes such as ³²P or ³⁵S (Sambrook, 1992) which can be detected by methods well known in the art such as autoradiography. Oligomer probes can also be labelled by non-radioactive methods such as chemiluminescent materials which can be detected by autoradiography (Sambrook, 1992). Also, enzyme-substrate based labelling and detection methods can be used. Labelling can be accomplished by mechanisms well known in the art such as end labelling (Sambrook, 1992), chemical labelling, or by hybridization with another labelled oligonucleotide. These methods of labelling and detection are provided merely as examples and are not meant to provide a complete and exhaustive list of all the methods known in the art.

The introduction of a label for detection purposes can be accomplished by attaching the label to the probe prior to hybridization.

An alternative method for practicing the method of the present invention includes the step of binding the target DNA to a solid support prior to the application of the probe. The solid support can be any material capable of binding the target DNA, such as beads or a membranous material such as nitrocellulose or nylon. After the target DNA is bound to the solid support, the probe oligomers is applied.

Functional assays can be used for detection of A-T carriers or affected individuals. For example, if the ATM protein product is shown to have PI 3-kinase biochemical activity which can be assayed in an accessible biological material, such as serum, peripheral leukocytes, etc., then homozygous normal individuals would have approximately normal biological activity and serve as the positive control. A-T carriers would have substantially less than normal biological activity, and affected (i.e. homozygous) individuals would have even less biological activity and serve as a negative control. Such a biochemical assay currently serves as the basis for Tay-Sachs carrier detection.

The present invention also provides a kit for diagnosis and detection of the defective A-T gene in populations. The kit includes a molecular probe complementary to genetic sequences of the defective gene which causes ataxia-telangiectasia (A-T) and suitable labels for detecting hybridization of the molecular probe and the defective gene thereby indicating the presence of the defective gene. The molecular probe has a DNA sequence complementary to mutant sequences in the population. Alternatively, the kit can contain reagents and antibodies for detection of mutant proteins.

The above discussion provides a factual basis for the use and identification of the ataxia-telangiectasia gene and gene products and identification of carriers as well as construction of transgenic organisms. The methods used in the present invention can be shown by the following non-limiting example and accompanying figures.

EXAMPLES Materials and Methods

General methods in molecular biology:

Standard molecular biology techniques known in the art and not specifically described were generally followed as in Sambrook et al., Molecular Cloning: A Laboratory Manual, Cold Springs Harbor Laboratory, New York (1989, 1992), and in Ausubel et al., Current Protocols in Molecular Biology, John Wiley and Sons, Baltimore, Md. (1989) and methodology as set forth in U.S. Pat. Nos. 4,666,828; 4,683,202; 4,801,531; 5,192,659 and 5,272,057. Polymerase chain reaction (PCR) was carried out generally as in PCR Protocols: A Guide To Methods And Applications, Academic Press, San Diego, Calif. (1990). Protein analysis techniques were as described in Coligan et al., Current Protocols in Immunology, John Wiley and Sons, Baltimore, Md. (1992, 1994).

Patient and family resources:

A cell line repository was established containing 230 patient cell lines and 143 cell lines from healthy members of Moroccan Jewish, Palestinian Arab and Druze families. Some of these pedigrees are highly inbred and unusually large (Ziv et al., 1991; Ziv, 1992). In view of the large number of meiotic events required for high-resolution linkage analysis, applicants collaborated with Dr. Carmel McConville (University of Birmingham, UK) and Dr. Richard Gatti (UCLA, Los Angeles, Calif.), who have also established extensive repositories of A-T families. Linkage analysis was conducted on a pool of 176 families.

EXAMPLE 1 Definition of the A-T Interval by Genetic Analysis

Studies based only on analysis of Israeli A-T families enabled localization of the A-T(C) gene at 11q22-23 (Ziv, 1991), and confirmed the localization of A-T(A) mutation in Palestinians to the same region (Ziv et al., 1992). Studies with the Birmingham group further narrowed the major A-T interval to 4 centimorgans, between D11S611 and D11S1897 (McConville et al., 1993), and subsequently to 3 centimorgans, between GRIA4 and D11S1897 (Ambrose et al., 1994; McConville et al., 1994; Shiloh, 1995, and FIG. 1).

All these studies were conducted with biallelic markers, whose power is limited by their low polymorphic information content (PIC). The recently discovered microsatellite markers based on variable numbers of tandem simple repeats (Litt and Luty, 1989; Weber and May, 1989) are much more powerful due to their high degree of polymorphism. Microsatellite markers were used to saturate the A-T region using two approaches. The first, was based on physical mapping of microsatellite markers generated by others which were loosely linked to chromosome 11q.

Mapping experiments were conducted using YAC and cosmid contigs which allowed precise, high-resolution localization of DNA sequences in this region of chromosome 11. Twelve microsatellites were localized at the A-T region (Vanagaite et al., 1994a; Vanagaite et al., 1995).

The second approach was based on generating new microsatellites within the YAC contig. A rapid method for the identification of polymorphic CA-repeats in YAC clones was set up (Rotman, 1995) resulting in the generation of twelve new markers within the A-T locus (Vanagaite et al., 1995; Rotman et al., 1995; Rotman et al., 1994b). Hence, the high-density microsatellite map constructed in this manner contained a total of 24 new microsatellite markers and spans the A-T locus and flanking sequences, over a total of six megabases (Vanagaite et al., 1995).

Repeated linkage analysis on the entire cohort of A-T families indicated that the A-T(A) locus was definitely located within a 1.5 megabase region between D11S1819 and D11S1818 (Gatti et al., 1994) as shown in FIG. 1 and in Shiloh (1995), with a clear peak of the cumulative lod score under D11S535 (Lange et al., 1994).

Concomitant with these studies, linkage disequilibrium (LD) analysis of Moroccan-Jewish A-T patients was conducted. LD refers to the non-random association between alleles at two or more polymorphic loci (Chakravarti et al., 1984). LD between disease loci and linked markers is a useful tool for the fine localization of disease genes (Chakravarti et al., 1984; Kerem et al. 1989; Ozelius et al., 1992; Sirugo et al., 1992; Hastbacka et al., 1992; Mitchison et al., 1993). LD is particularly powerful in isolated ethnic groups, where the number of different mutations at a disease locus is likely to be low (Hastbacka et al., 1992; Lehesjoki et al., 1993; Aksentijevitch et al., 1993). Early on, applicants observed very significant LD (p<0.02-p<0.001) between A-T and markers along the D11S1817-D11S927 region in the patients of the sixteen Moroccan-Jewish A-T families identified in Israel (Oskato et al., 1993). Further analysis with the new markers narrowed the peak of linkage disequilibrium to the D11S384-D11S1818 region as shown in FIG. 1.

Haplotype analysis indicated that all of the mutant chromosomes carry the same D11S384-D11S1818 haplotype, suggesting a founder effect for A-T in this community, with one mutation predominating.

EXAMPLE 2 SEQUENCING THE ATM GENE

Cloning the disease locus in a contig (set of overlapping clones) was essential in isolating the. A-T disease gene. The entire A-T locus and flanking region in a contig of yeast artificial chromosomes (YACs) was cloned by methods well known in the art (Rotman et al. 1994c; Rotman et al., 1994d). This contig was instrumental in the construction of the microsatellite map of the region (Vanagaite et al., 1995) and subsequently enabled construction of cosmid contigs extending over most of the interval D11S384-D11S1818. Cosmids corresponding to the YAC clones were identified in a chromosome 11-specific cosmid library supplied by Dr. L. Deaven (Los Alamos National Laboratory) and were ordered into contigs by identifying overlaps as shown in FIG. 1.

Isolation of the A-T gene:

Transcribed sequences were systematically identified based on two complementary methods:

1. Use of an improved direct selection method based on magnetic bead capture (MBC) of cDNAs corresponding to genomic clones (Morgan et al., 1992; Tagle et al., 1993). In several, large-scale experiments YAC or cosmid DNA was biotinylated and hybridized to PCR-amplified cDNA from thymus, brain and placenta. Genomic DNA-cDNA complexes were captured using streptavidin-coated magnetic beads which was followed with subsequent elution, amplification, and cloning of captured cDNAs. The cDNA inserts were excised from a gel, self-ligated to form concatamers and sonicated to obtain random fragments. These fragments were size fractionated by gel electrophoresis, and the 1.0-1.5 Kb fraction was extracted from the gel and subcloned in a plasmid vector. The end portions of individual clones were sequenced using vector-specific primers, in an automated sequencer (Model 373A, Applied Biosystems), and the sequences were aligned using the AutoAssembler program (Applied Biosystems Division, Perkin-Elmer Corporation). In the final sequence each nucleotide position represents at least 3 independent overlapping readings.

YACs were also used and were no less efficient than cosmids as starting material for MBC, with more than 50% of the products mapping back to the genomic clones. However, when a small panel of radiation hybrids spanning the A-T region was used to test the cDNA fragments, it was found that some clones that hybridized back to the. YACs and cosmids were not derived from this region. This pitfall probably stems from limited homology between certain portions of different genes, and points up the necessity to use radiation hybrid mapping when testing the authenticity of the captured sequences, and not to rely solely on cloned DNA for this purpose.

Homology searches in sequence databases showed that only one of the first 105 cDNA fragments mapped to the A-T region was homologous to a sequence previously deposited in one of the databases, as an expressed sequence tag (EST).

2. Exon amplification, also termed “exon trapping” (Duyk et al., 1990; Buckler et al., 1991), is based on cloning genomic fragments into a vector in which exon splice sites are flagged by splicing to their counterpart sites in the vector. This method of gene identification was expected to complement the MBC strategy, since it does not depend on the constitution of cDNA libraries or on the relative abundance of transcripts, and is not affected by the presence of repetitive sequences in the genomic clones. An improved version of this system (Church et al., 1993) that eliminated problems identified in an earlier version, including a high percentage of false positives and the effect of cryptic splice sites was utilized. Each experiment ran a pool of three to five cosmids with an average of two to five exons identified per cosmid. A total of forty five exons were identified.

Sequence analysis and physical mapping indicated that MBC and exon amplification were complementary in identifying transcribed sequences.

The availability of a deep cosmid contig enabled rapid and precise physical localization of the cDNA fragments and captured exons, leading to a detailed transcriptional map of the A-T region.

Both MBC and exon amplification yielded short (100-1000 bp) transcribed sequences. Those sequences were used as anchor points in isolating full-length clones from twenty eight cDNA libraries currently at applicants disposal and which represented a variety of tissues and cell lines.

Initial screening of the cDNA libraries by polymerase chain reaction (PCR) using primer sets derived from individual cDNA fragments or exons aided in the identification of the libraries most likely to yield corresponding cDNA clones.

Large scale screening experiments were carried out in which most of the cDNA fragments and exons were used in large pools. In addition to the mass screening by hybridization, PCR-based screening methods and RACE (rapid amplification of cDNA ends) (Frohman et al., 1988; Frohman et al., 1994) was employed to identify full-length cDNAs.

The above experiments resulted in the initial identification and isolation of a cDNA clone designated 7-9 (Savitsky et al, 1995a), the complete sequence of which is set forth in SEQ ID No:1 and which is derived from a gene located under the peak of cumulative location score obtained by linkage analysis as shown in FIG. 1. The gene extends over some 300 kilobases (kb) of genomic DNA and codes for two major mRNA species of 12 kb and 10.5 kb in length. The 7-9 clone is 5.9 kb in length and, therefore, is not a full length clone.

An open reading frame of 5124 bp within this cDNA encodes a protein with signature motifs typical of a group of signal transduction proteins known as phosphatidylinositol 3-kinases (PI 3-kinases). PI 3-kinases take part in the complex system responsible for transmitting signals from the outer environment of a cell into the cell. It is not clear yet whether the protein product of the corresponding gene encodes a lipid kinase or a protein kinase.

The gene encoding the 7-9 cDNA clone was considered a strong A-T candidate and mutations were sought in patients. Southern blotting analysis revealed a homozygous deletion in this gene in affected members of Family N., an extended Palestinian Arab A-T family which has not been assigned to a specific complementation group. All the patients in this family are expected to be homozygous by descent for a single A-T mutation. The deletion includes almost the entire genomic region spanned by transcript 7-9, and was found to segregate in the family together with the disease. This finding led to a systematic search for mutations in the 7-9 transcript in additional patients, especially those previously assigned to specific complementation groups.

The restriction endonuclease fingerprinting (REF) method (Liu and Sommer 1995) was applied to reverse-transcribed and PCR-amplified RNA (RT-PCR) from A-T cell lines. Observation of abnormal REF patterns was followed by direct sequencing of the relevant portion of the transcript and repeated analysis of another independent RT product. In compound heterozygotes, the two alleles were separated by subcloning of RT-PCR products and individually sequenced. Genomic sequencing was conducted in some cases to confirm the sequence alteration at the genomic level. Additional family members were studied when available.

Ten sequence alterations (Table 1) were identified in the 7-9 transcript in 13 A-T patients including two sibling pairs. Most of these sequence changes are expected to lead to premature truncation of the protein product, while the rest are expected to create in-frame deletions of 1-3 amino acid residues in this protein. While the consequences of the in-frame deletions remain to be investigated, it is reasonable to assume that they result in impairment of protein function. In one patient, AT3NG, the loss of a serine residue at position 1512 occurs within the PI3-kinase signature sequence. This well conserved domain is distantly related to the catalytic site of protein kinases, hence this mutation is likely to functionally affect the 7-9 protein.

In view of the strong evidence that mutations in this gene are responsible for A-T, it was designated ATM (A-T, Mutated). Since these patients represent all complementation groups of the disease and considerable ethnic variability, these results indicate that the ATM gene alone is responsible for all A-T cases.

In order to complete the cloning of the entire ATM open reading frame, fetal brain and colon random-primed libraries obtained from Stratagene (San Diego, Calif.) and an endothelial cell random-primed library (a gift of Dr. David Ginsburg, University of Michigan) were screened. A total of 1×10⁶ pfu were screened at a density of 40,000 pfu per 140 mm plate, and replicas were made on Qiabrane filters (Qiagen), as recommended by the manufacturer. Filters were prehybridized in a solution containing 6×SSC, 5×Denhardt's, 1% N-laurylsarcosyl, 10% dextran sulfate and 100 μg/ml salmon sperm DNA for 2 hours at 65° C. Hybridization was performed for 16 hrs under the same conditions with 1×10⁶ cpm/ml of ³²P-labelled probe, followed by final washes of 30 minutes in 0.25×SSC, 0.1%SDS at 60° C. Positive clones were plaque-purified using standard techniques and sequenced. DNA sequencing was performed using an automated DNA sequencer (Applied Biosystems, model 373A), and the sequence was assembled using the AutoAssembler program (Applied Biosystems Division, Perkin-Elmer Corporation). In the final sequence, each nucleotide represents at least four independent readings in both directions.

Database searches for sequence similarities were performed using the BLAST network service. Alignment of protein sequences and pairwise comparisons were done using the MACAW program, and the PILEUP and BESTFIT programs in the sequence analysis software package developed by the Genetics Computer Group at the University of Wisconsin.

EXAMPLE 3 DETECTION OF MUTATIONS

Determination of mutations:

The recently discovered ATM gene is probably involved in a novel signal transduction system that links DNA damage surveillance to cell cycle control. A-T mutations affect a variety of tissues and lead to cancer predisposition. This striking phenotype together with the existence of “partial A-T phenotypes” endow the study of ATM mutations with special significance.

MATERIALS AND METHODS

RT-PCR:

Total RNA was extracted from cultured fibroblast or lymphoblast cells using the Tri-Reagent system (Molecular research Center, Cincinnati, Ohio). Reverse transcription was performed on 2.5 ug of total RNA in a final volume of 10 ul, using the Superscript II Reverse Transcriptase (Gibco BRL, Gaithersburg, Md.) in the buffer recommended by the supplier, and in the presence of 125 U/ml of RNAsin (Promega) and 1 mM dNTPs (Pharmacia). Primers were either oligo(dT) (Pharmacia) or a specifically designed primer. The reaction products were used as templates for PCR performed with specific primers. These reactions were carried out in 50 μl containing 2 units of Taq DNA Polymerase (Boehringer Mannheim, Mannheim, Germany), 200 μM dNTPs, 0.5 μM of each primer, and one tenth of the RT-PCR products. The products were purified using the QIA-quick spin system (Qiagen, Hilden, Germany).

Restriction endonuclease fingerprinting:

The protocol of Liu and Sommer (1995) was followed with slight modifications. RT-PCR was performed as described above, using primers defining PCR products of 1.0-1.6 kb. One hundred ng of amplified DNA was digested separately with 5 or 6 restriction endonucleases in the presence of 0.2 units of shrimp alkaline phosphatase (United States Biochemicals, Cleveland, Ohio). Following heat inactivation at 65° C. for 10 minutes, the digestion products corresponding to the same PCR product were pooled, denatured at 96° C. for 5 minutes and immediately chilled on ice. Ten ng of this fragment mixture was labeled in the presence of 6 μCi of [γ-³³P]ATP and 1 unit of T4 polynucleotide kinase (New England Biolabs, Beverly, Mass.) at 37° C. for 45 minutes. Twenty μl of stop solution containing 95% formamide, 20 mM EDTA, 0.05% bromophenol blue, 0.05% xylene cyanol, and 10 mM NaOH were added, and the samples were boiled for 3 minutes and quick-chilled on ice. Electrophoresis was performed in 5.6% polyacrylamide gels in 50 mM Tris-borate, pH 8.3, 1 mM EDTA at constant power of 12 W for 3 hours at room temperature, with a fan directed to the glass plates, keeping them at 22-24° C. The gels were dried and subjected to autoradiography.

Direct sequencing of PCR products:

Five hundred ng of PCR products was dried under vacuum, resuspended in reaction buffer containing the sequencing primer, and the mixture was boiled and snap-frozen in liquid nitrogen. The Sequenase II system (Unites States Biochemicals) was used to carry out the sequencing reaction in the presence of 0.5 μg of single-strand binding protein (T4 gene 32 protein, United States Biochemicals). The reaction products were treated with 0.1 μg of proteinase K at 65° C. for 15 minutes, separated on a 6% polyacrylamide gel, and visualized by autoradiography.

Using the methods described herein above the ATM transcript was scanned for mutations in fibroblast and lymphoblast cell lines derived from an extended series of A-T patients from 13 countries, all of whom were characterized by the classical A-T phenotype. The analysis was based on RT-PCR followed by restriction endonuclease fingerprinting (REF). REF is a modification of the single-strand conformation polymorphism (SSCP) method, and enables efficient detection of sequence alterations in DNA fragments up to 2 kb in length (Liu and Sommer, 1995).

Briefly, after PCR amplification of the target region, multiple restriction endonuclease digestions are performed prior to SSCP analysis, in order to increase the sensitivity of the method and enable precise localization of a sequence alteration within the analyzed fragment. The coding sequence of the ATM transcript, which spans 9168 nucleotides (SEQ ID No:2) (Savitsky et al., 1995b), was thus divided into 8 partly overlapping portions of 1.0-1.6 Kb, and each one was analyzed separately. Sequence alterations causing. abnormal REF patterns were located and disclosed by direct sequencing. Mutations identified in this way were reconfirmed by repeating the RT-PCR and sequencing, or by testing the presence of the same mutations in genomic DNA.

In compound heterozygotes, the two alleles were separated by subcloning and individually sequenced. In some cases, agarose gel electrophoresis showed large deletions in the ATM transcript manifested as RT-PCR products of reduced sizes. The breakpoints of such deletions were delineated by direct sequencing of these products.

The 44 mutations identified to date in our patient cohort (Table 2) include 34 new ones and 10 previously published ones (Table 1). (Mutations in Table 2 are presented according to the nomenclature proposed by Beaudet & Tsui (1993); nucleotide numbers refer to their positions in the sequence of the ATM transcript (accession number U33841); the first nucleotide of the open reading frame was designated +1.) These mutations were found amongst 55 A-T families: many are unique to a single family, while others are shared by several families, most notably the 4 nt deletion, 7517del4, which is common to 6 A-T families from South-Central Italy (Table 2). According to this sample, there is a considerable heterogeneity of mutations in A-T, and most of them are “private”. The proportion of homozygotes in this sample is relatively high due to a high degree of consanguinity the populations studied. It should be noted, however, that apparently homozygous patients from non-consanguineous families may in fact be compound heterozygotes with one allele not expressed.

This series of 44 A-T mutations is dominated by deletions and insertions. The smaller ones, of less than 12 nt, reflect identical sequence alterations in genomic DNA. Deletions spanning larger segments of the ATM transcript were found to reflect exon skipping, not corresponding genomic deletions. This phenomenon usually results from sequence alterations at splice junctions or within introns, or mutations within the skipped exons, mainly of the nonsense type (Cooper and Krawczak, 1993; Sommer, 1995; Steingrimsdottir et al., 1992; Gibson et al., 1993; Dietz and Kendzior, 1994). One large deletion spans about 7.5 Kb of the transcript and represents a genomic deletion of about 85 Kb within the ATM gene. Of these deletions and insertions, 25 are expected to result in frameshifts. Together with the 4 nonsense mutations, truncation mutations account for 66% of the total number of mutations in this sample. Seven in-frame deletions span long segments (30-124 aa) of the protein, and similarly to the truncation mutations, are expected to have a severe effect on the protein's structure. It should be noted that two base substitutions abolish the translation initiation and termination codons. The latter is expected to result in an extension of the ATM protein by an additional 29 amino acids. This mutation may affect the conformation of the nearby PI 3-kinase-like domain.

While the effect of the 4 small (1-3 aa) in-frame deletions and insertions on the ATM protein remains to be studied, it should be noted that one such deletion (8578del3) leads to a loss of a serine residue at position 2860. This amino acid is part of a conserved motif within the PI 3-kinase-like domain typical of the protein family to which ATM is related, and is present in 7 of 9 members of this family. The single missense mutation identified in this study, which leads to a Glu2904Gly substitution, results in a nonconservative alteration of another extremely conserved residue within this domain, which is shared by all of these proteins. The patient homozygous for this mutation, AT41RM, shows the typical clinical A-T phenotype. Measurement of radioresistant DNA synthesis in the patient's cell line revealed a typical A-T response, demonstrating that this patient has the classical A-T cellular phenotype.

As discussed herein above, the ATM gene of the present invention is probably involved in a novel signal transduction system that links DNA damage surveillance to cell cycle control. A-T mutations affect a variety of tissues and lead to cancer predisposition. This striking phenotype together with the existence of “partial A-T phenotypes” endow the study of ATM mutations with special significance.

The ATM gene leaves a great deal of room for mutations: it encodes a large transcript. The variety of mutations identified in this study indeed indicates a rich mutation repertoire. Despite this wealth of mutations, their structural characteristics point to a definite bias towards those that inactivate or eliminate the ATM protein. The nature or distribution of the genomic deletions among these mutations do not suggest a special preponderance of the ATM gene for such mutations, such as that of the dystrophin (Anderson and Kunkel, 1992) or steroid sulfatase (Ballabio et al., 1989) genes which are particularly prone to such deletions. Thus, one would have expected also a strong representation of missense mutations, which usually constitute a significant portion of the molecular lesions in many disease genes (Cooper and Krawczak, 1993; Sommer, 1995). However, only one such mutation was identified in the present study. Other point mutations reflected in this series are those that probably underlie the exon skipping deletions observed in many patients, again, exerting a severe structural effect on the ATM protein.

A technical explanation for this bias towards deletions and insertions could be a greater ability of the REF method to detect such lesions versus its ability to detect base substitution. Liu and Sommer (1995) have shown, however, that the detection rate of this method in a sample of 42 point mutations in the factor IX gene ranged between 88% and 100%, depending on the electrophoresis conditions. The 7 base substitutions detected directly by the REP method in the present study (Table 2), indicate that such sequence alterations are detected in our hands as well.

Since the expected result of most of these mutations is complete inactivation of the protein, this skewed mutation profile might represent a functional bias related to the studied phenotype, rather than a structural feature of the ATM gene that lends itself to a particular mutation mechanism. The classical A-T phenotype appears to be caused by homozygosity or compound heterozygosity for null alleles, and hence is probably the most severe expression of defects in the ATM gene. The plethora of missense mutations expected in the large coding region of this gene is probably rarely represented in patients with classical A-T, unless such a mutation results in complete functional inactivation of the protein. By inference, the only missense identified in this study, Glu2940Gly, which substitutes a conserved amino acid at the PI 3-kinase domain and clearly gives rise to a classical A-T phenotype, points to the importance of this domain for the biological activity of the ATM protein. Mutations in this domain abolish the telomere-preserving function of the TEL1 protein in S. cerevisiae (Greenwell et al., 1995), a protein which shows a particularly high sequence similarity to ATM (Savitsky et al., 1995b; Zakian, 1995). Another member of the family of PI 3-kinase-related proteins that includes ATM is the mammalian FRAP. Mutations in the PI 3-kinase domain abolish its autophosphorylation ability and biological activity (Brown et al., 1995). These observations, together with the mutation shown here, suggest that this domain in ATM is also likely to include the catalytic site, which may function as a protein kinase.

Genotype-phenotype relationships associated with the ATM gene appear therefore to extend beyond classical A-T. There are several examples of genes in which different mutations lead to related but clinically different phenotypes. For example, different combinations of defective alleles of the ERCC2 gene may result in xeroderma pigmentosum (group D), Cockayne's syndrome or trichothiodystrophy—three diseases with different clinical features involving UV sensitivity (Broughton et al., 1994, 1995).

Different mutations in the CFTR gene may lead to full-fledged cystic fibrosis, or only to congenital bilateral absence of the vas deferens which is one feature of this disease (Chillon et al., 1995; Jarvi et al., 1995). A particularly interesting example is the X-linked WASP gene responsible for Wiskott Aldrich syndrome (WAS), characterized by immunodeficiency, eczema and thrombocytopenia. Most of the mutations responsible for this phenotype cause protein truncations; however, certain missense mutations may result in X-linked thrombocytopenia, which represents a partial WAS phenotype, while compound heterozygosity for a severe and mild mutation results in females in an intermediate phenotype (Kolluri et al., 1995; Derry et al., 1995).

In a similar manner, genotypic combinations of mutations with different severities create a continuous spectrum of phenotypic variation in many metabolic diseases.

Which phenotypes are most likely to be associated with milder ATM mutations? Since cerebellar damage is the early and severe manifestation of A-T, it is reasonable to assume that the cerebellum might also be affected to some extent in phenotypes associated with milder ATM mutations. Such phenotypes may include cerebellar ataxia, either isolated (Harding, 1993) or coupled with various degrees of immunodeficiency. The latter combination has indeed been described, sometimes with chromosomal instability, and is often designated “ataxia without telangiectasia” (Ying and Decoteau, 1983; Byrne et al., 1984; Aicardi et al., 1988; Maserati, 1988; Friedman and Weitberg, 1993). Friedman and Weitberg (1993) recently suggested a new clinical category of “ataxia with immune deficiency” that would include A-T as well as other cases of cerebellar degeneration with immune deficits. Evaluation of patients with cerebellar disorders with the present invention may reveal a higher frequency of such cases than previously estimated. However, in view of the pleiotropic nature of the ATM gene, the range of phenotypes associated with various ATM genotypes may be even broader, and include mild progressive conditions not always defined as clear clinical entities. Screening for mutations in this gene in such cases may reveal wider boundaries for the molecular pathology associated with the ATM gene.

EXAMPLE 4 Identification of the Mouse Atm Gene MATERIALS AND METHODS

Library screening:

An oligo(dT)-primed mouse brain cDNA library in a Uni-Zap XR vector, a mouse 129Sv genomic library (Stratagene, San Diego, Calif.) and a randomly primed mouse brain cDNA library in lambda-gt10 (Clontech, Palo Alto, Calif.) were used. 10⁶ pfu were screened with each probe. The libraries were plated at a density of 5×10⁴ pfu per 140 mm plate, and two sets of replica filters were made using Qiabrane nylon membranes (Qiagen, Hilden, Germany) according to the manufacturer's instructions. Filters were prehybridized for 2 hours at 65° C. in 6×SSC, 5×Denhardt's, 1% N-laurylsarcosyl, 10% dextran sulfate and 100 μg/ml sheared salmon sperm DNA. Hybridization was performed at 65° C. for 16-18 hours in the same solution containing 10⁶ cpm/ml of probe labeled with ³²P-dCTP by random priming. Final washes were made for 30 minutes in 0.5×SSC, 0.1% SDS at 50° C. Positive clones were plaque-purified using standard techniques.

RT-PCR:

First strand synthesis was performed using 2 μg of total RNA from mouse 3T3 cells with an oligo(dT) primer and Superscript II (Gibco-BRL, Gaithersburg, Md.). The reaction products served as templates for PCR with gene-specific primers.

Sequence analysis:

The insert of cDNA clone 15-1 (see below) was excised from a gel, self-ligated to form concatamers, and sonicated to obtain random fragments. These fragments were size-fractionated by gel electrophoresis, and the 1.0- to 1.5-kb fraction was extracted from the gel and subcloned in a pBluescript vector (Stratagene). The end portions of individual clones were sequenced with vector-specific primers in an automated sequencer (Model 373A, Applied Biosystems Division, Perkin Elmer), and the sequences were aligned with the AutoAssembler program (Applied Biosystems). In the final sequence, each nucleotide position represents at least three independent overlapping readings. In smaller cDNA inserts, sequencing was initiated with vector-specific primers, and additional sequencing primers were designed for both strands as sequencing progressed. Sequencing of RT-PCR products was performed with the PCR primers.

Fluorescence in-situ hybridization (FISH):

Preliminary chromosomal localization of the Atm gene was determined by FISH analysis. Mouse metaphase chromosomes were prepared from concanavalin A (conA) stimulated lymphocytes obtained after splenectomy as described by Boyle at al. (1992), with slight modifications. Briefly, homogenized spleen tissue was cultured for 48 hours in RPMI 1640 medium supplemented with 20% fetal bovine serum, 6 μg/ml concanavalin A, and 86.4 μM β-mercaptoethanol. The cell cycle was synchronized by incubation with methotrexate (17 hours, 4.5 mM). The S-phase block was released with BrdU (30 μM) and FUdR (0.15 μg/ml) for 5 hours. Colcemid was added for 10 minutes; the cells were incubated in KCl (0.55%) and fixed with methanol/acetic acid (3:1). The mouse Atm genomic clone used for FISH analysis was obtained by screening the mouse 129Sv genomic library with a human 236 bp PCR probe corresponding to nt 5381-5617 of the human ATM cDNA. Sequence analysis confirmed that this clone contains a 177 bp exon corresponding to nt 5705-5881 of the mouse Atm cDNA.

The mouse Atm genomic clone was labeled by nick-translation with digoxigenin-11dUTP (Boehringer Mannheim, Indianapolis, Ind.). To facilitate chromosome identification, a biotinylated mouse chromosome 9-specific painting probe (Vector Laboratories, Burlingame, Calif.) was used for cohybridization. The probe sequences and metaphase chromosomes were heat denatured separately. Hybridization was performed for 15 hours at 37° C. in a solution containing 50% formamide, 2×SSC, and 10% dextran sulfate. Post-hybridization washes were performed as described by Ried et al. (1992). The biotinylated probe sequences were detected by incubation with avidin conjugated to FITC (Vector Laboratories), and the digoxigenin labeled sequences by incubation with mouse anti-digoxin and goat anti-mouse conjugated to TRITC (Sigma Chemicals, St. Louis, Mo.). Chromosomes were counterstained with DAPI. The fluorescent signals were sequentially acquired using a cooled CCD camera (Photometrics, Tucson, Ariz.) coupled to a Leica DMRBE microscope. Gray scale images were converted to tintscale using Gene Join (Ried et al., 1992).

Linkage analysis:

Interspecific backcross progeny were generated by mating (C57BL/6J×M. spretus)F1 females and C57BL/6J males, as described by Copeland and Jenkins (1991). A total of 205 N₂ mice were used to map the Atm locus as described herein below. Southern blot analysis was performed (Jenkins et al., 1982). All blots were prepared with Hybond-N⁺ membrane (Amersham). The Atm probe, REF3, a PCR-amplified fragment from the Atm mouse cDNA representing nt 6000-7264 was labeled with [α³²P]dCTP using a random priming labeling kit (Stratagene); washing was done to a final stringency of 0.5×SSCP, 0.1% SDS, 65° C. Fragments of 4.9, 3.6, and 1.4 kb were detected in HindIII-digested C57BL/6J DNA and fragments of 5.6 and 4.3 kb were detected in HindIII-digested M. spretus DNA. The presence or absence of the 5.6 and 4.3 kb M. spretus-specific fragments, which cosegregated, were followed in the backcross mice.

A description of the probes and RFLPs for the loci linked to Atm, including glutamate receptor, ionotropic, kainate 4 (Grik4); thymus cell antigen-1 theta (Thy1); Casitas B-lineage lymphoma (Cbl); CD3 antigen, gamma polypeptide (Cd3g); and dopamine receptor 2 (Drd2), has been reported previously (Kingsley at al., 1989; Regnier et al., 1989; Szpirer et al., 1994). The mouse chromosomal locations of mitochondrial acetoacetyl-CoA thiolase (Acat1) and src-kinase (Csk) were determined for the first time, herein. Recombination distances were calculated as described (Green, 1981), using the computer program SPRETUS MADNESS. Gene order was determined by minimizing the number of recombination events required to explain the allele distribution patterns.

The Csk probe, a 2.2 kb EcoRI/XhoI fragment derived from the mouse cDNA (Thomas et al., 1991), was labeled with [α³²P]dCTP using a nick] translation labeling kit (Boehringer Mannhein); washing was done to a final stringency of 0.1×SSPE, 0.1% SDS, 65° C. A fragment of 9.4 kb was detected in HindIII-digested C57BL/6J DNA and a fragment of 5.8 kb was detected in HindIII-digested M. spretus DNA. The presence or absence of the 5.8 kb M. spretus-specific fragment was followed in the backcross mice. The Acat1 probe, a 1.4 kb fragment from the Acat rat cDNA (Fukao et al., 1990), was labeled by nick translation and washed from the blots to a final stringency of 0.8×SSCP, 0.1% SDS, 65° C. A fragment of 23 kb was detected in EcoRI-digested C57BL/6J DNA, and fragments of 22 and 5.4 kb were detected in EcoRI-digested M. spretus DNA. The presence or absence of the 22 and 5.4 kb M. spretus-specific fragments, which cosegregated, were followed in the backcross mice.

RESULTS

Molecular cloning of the coding sequence of Atm gene:

In search of a cDNA clone derived from a murine gene corresponding to the human ATM, 10⁶ pfu from a mouse brain cDNA library were screened with a PCR product corresponding to nt 4021-8043 of the human ATM cDNA (Savistky et al., 1995b; the first nucleotide of the open reading frame was numbered 1). Fifteen positive clones were identified, and the longest one, of 8.5 kb (designated 15-1; FIG. 3), was further analyzed. High-stringency hybridization of this clone to panels of radiation hybrids, YAC and cosmid clones representing the human ATM locus (Rotman et al.,1994; Shiloh, 1994; Savitsky et al., 1995a,b) showed strongly hybridizing sequences within the ATM locus. Northern blotting analysis and subsequent sequencing and alignment with the human ATM transcript confirmed that 15-1 corresponded throughout its length to the human gene but was missing the 5′ end of the corresponding mouse transcript.

Screening of a randomly primed mouse brain cDNA library with a probe corresponding to the 5′ region of the human ATM transcript (nt 1-2456) identified 2 clones, MRP1 and MRP2, of 1.3 and 0.6 kb, respectively (FIG. 3). The gap between clones 15-1 and MRP1 was subsequently bridged using RT-PCR with primers derived from these clones, which produced the fragment m4m5 of 840 bp. Finally, a primer derived from the MRP1 sequence was designed and used with vector-specific primers to obtain two PCR products, 23m9 and 24m9, from the randomly primed brain cDNA library. All these clones and PCR products hybridized exclusively to the ATM locus in the human genome. Their sequences were assembled and formed a contig of 9620 nucleotides (FIG. 3; GenBank accession no. U43678).

Sequence comparisons:

The sequence of the contig shown in FIG. 3 shows an open reading frame (ORF) of 9201 nt, and includes a 41 nt 5′ UTR and a 378 nt 3′ UTR. These UTRs are probably not complete, in view of the length of the UTRs of the ATM transcript and the lack of a poly(A) tail in 15-1. The ORF encodes a putative protein of 3,066 amino acids with a molecular weight of 349.5 kDa (SEQ ID No:3). When the nucleotide and amino acid sequences corresponding to the coding regions of the mouse and human ATM transcripts were aligned, there was an overall identity of 85% at the nucleotide sequence level, and an 84% identity and 91% similarity at the amino acid level. The difference of 10 amino acids between the human and mouse proteins is the net sum of several insertions and deletions in both proteins, when compared to each other. The PI 3-kinase domain found in ATM and other related proteins was identified in the mouse sequence (SEQ ID No:12, aa residues 2750-3055), as was the leucine zipper (SEQ ID No:12, aa residues 1211 to 1243) present in the human ATM protein (SEQ ID No:3, aa residues 2855-2875 and 1217-1238 respectively).

These results indicated that applicants had obtained the entire coding sequence of Atm, the murine homolog of the human ATM gene. It is noteworthy that the human and mouse proteins were most similar within the PI 3-kinase domain at the carboxy terminus (94% identity, 97% similarity), while the other portions of these proteins show variable identity and similarity reaching a minimum of 70% and 82%, respectively, in some regions (FIG. 4).

Expression pattern:

A Northern blot representing several mouse tissues (Clontech) was probed with a fragment representing nt 2297-5311 of the Atm transcript. This probe identified a message of about 13 kb in brain, skeletal muscle and testis, which was barely detectable in heart, spleen, lung and kidney. In the testis, another band of about 10.5 kb was observed at about 50% intensity compared to the 13 kb band. This pattern seems to represent greater differences in expression levels between tissues, compared to the more uniform pattern observed in human tissues (Savitsky et al., 1995a). In addition, the 10.5 kb band, which may represent mRNA species with alternative polyadenylation, was not detected in any of 16 human tissues tested previously, but was clearly observed in cultured human fibroblasts (Savitsky et al., 1995a).

Chromosomal localization of the Atm gene by FISH:

Initial chromosomal localization of the mouse Atm gene was determined by dual-color FISH. A digoxigenin-labeled probe was cohybridized with a chromosome painting probe specific for mouse chromosome 9, that confirms the identification of DAPI-stained mouse chromosomes. Mouse chromosome 9 contains homologous regions of human chromosomes 11q, including 11q22-23, the region to which the human ATM gene was assigned. Twelve randomly selected metaphases were analyzed. Signals were observed in 90% of the cells on mouse chromosome 9C. Other chromosomal positions were not observed.

Genetic mapping of the Atm gene:

The Atm gene was further localized on the genetic map of mouse chromosome 9 using interspecific backcross analysis using progeny derived from matings of [(C57BL/6J×M. spretus) F₁×C57BL/6J] mice. This interspecific backcross mapping panel has been typed for over 2000 loci which are well distributed among all the autosomes as well as the X chromosome (Copeland and Jenkins, 1991). C57BL/6J and M. spretus DNAs were digested with several enzymes and analyzed by Southern blot hybridization for informative restriction fragment length polymorphisms (RFLPs), using a probe representing nt 6000-7264 of the Atm transcript.

The results indicated that Atm is located in the proximal region of mouse chromosome 9 linked to Grik4, Thy1, Cbl, C3g, Drd2, Acat1 and Csk (FIG. 5B). Ninety-one mice were analyzed for every marker and are shown in the segregation analysis (FIG. 5A), however up to 203 mice were typed for some pairs of markers. Each locus was analyzed in pairwise combinations for recombination frequencies using the additional data. The ratios of the total number of mice analyzed for each pair of loci and the recombination frequencies between the loci are shown in FIG. 5B.

Two mapping methods were used to assign the Atm gene to chromosome 9, band 9C. Comparative gene mapping in mouse and human has revealed numerous regions of homology between the two species (Copeland et al., 1993). (References for the human map positions of loci cited in this study can be obtained from GDB (Genome Database), a computerized database of human linkage information maintained by The William H. Welch Medical Library of The Johns Hopkins University (Baltimore, Md.).) This is clearly demonstrated between this portion of mouse chromosome 9 and human chromosome 11q22-23. The human homologs of Grik4, Thy1, Cbl, Cd3g, Drd2, Acat1 and Atm map to 11q22-23. It is noteworthy that, similarly to the close map locations of Atm and Acat1 in the mouse, ATM and ACAT1 lie about 200 kb apart in the human genome. The mapping of Atm refines the distal end of the human 11q22-23 homology unit. Csk, 1.1 cM distal to Acat and Atm, maps to human chromosome 15q23-q25. The average length of a conserved autosomal segment in mice was estimated at 8.1 cM (Nadeau and Taylor, 1984). The conserved segment on mouse chromosome 9 which corresponds to 11q22-23 in humans, extends centromeric to Grik4 and spans approximately 19 cM.

The high degree of conservation between the human and mouse proteins suggests similar roles; however, the difference in expression patterns between mice and humans suggested by these northern results may lead to differences between the phenotypes associated with these proteins in the two organisms. To date, no phenotype identical to A-T has been reported in the mouse.

The derived chromosome 9 interspecific map of the present invention was compared with a composite mouse linkage map from Mouse Genome Database (The Jackson Laboratory, Bar Harbor, Me.), that reports location of many uncloned mouse mutations. Only one uncloned mouse mutation, luxoid (lu), lies in the vicinity of Atm, but this skeletal abnormality is highly unlikely to represent a mouse disorder corresponding to A-T. The mouse phenotype closest to A-T is severe combined immune deficiency (SCID) on mouse chromosome 16. It is characterized by a deficiency in mature B and T lymphocytes, radiation sensitivity, chromosomal instability, defective rejoining of DNA double-strand breaks and defective V(D)J recombination (Bosma and Carroll, 1991). This phenotype is caused by defects in one of the proteins with a PI 3-kinase domain, the catalytic subunit of DNA-dependent protein kinase (DNA-PKcs) (Blunt et al., 1995; Hartley et al., 1995). The reason for lack of a mouse phenotype associated with the Atm gene may be that, unlike in humans, such a phenotype is either embryonic lethal, or considerably milder than in humans. As described herein below, a knockout mouse for the Atm gene in mice has been generated and the phenotype appears in young mice to be somwhat milder than in humans.

Using a 200 bp PCR product from the human ATM sequence, mouse genomic clones were screened and isolated. The sequence of the 200 bp PCR product corresponds approximately to ATM exons 40 and 41 as set forth in SEQ ID No:24. The targeted disruption of the homologous mouse gene (Atm) involves insertion of a neomycin cassette in the targeted exon and homologous recombination in 129/Sv-ES cells. Generation and analysis of knockout mice were done in collaboration with Dr. Anthony Wynshaw-Boris at the NIH. Neomycin resistant clones were analyzed by PCR and Southern, and injected into blastocysts. Targeted ES cells showed moderate radiosensitivity. No outward phenotypic differences were observed in the heterozygous progenies thus far. Heterozygous matings resulted in homozygote nulls whose preliminary analysis are shown to be infertile, are radiosensitive and show stunted growth. Techniques used are as described in Hogan et al., Manipulating the Mouse Embryo: A Laboratory Manual, Cold Spring Harbor Laboratory, New York, (1994).

EXAMPLE 5 Generation of Antibodies Against the ATM Protein

Antibodies, both polyclonal and monoclonal, were generated against peptide sequences based on the human ATM sequence as set forth in SEQ ID Nos:4-7,13-15:

HEPANSSASQSTDLC (SEQ ID No:4),

CKRNLSDIDQSFDKV (SEQ ID No:5),

PEDETELHPTLNADDQEC (SEQ ID No:6),

CKSLASFIKKPFDRGEVESMEDDTNG (SEQ ID No:7),

CRQLEHDRATERRKKEVEKFK (SEQ ID No:13)

CLRIAKPNVSASTQASRQKK (SEQ ID No:14)

CARQEKSSSGLNHILAA (SEQ ID No:15)

Two rabbits each and six mice each were immunized with each of the antigens.

Additional peptide sequences based on the mouse atm sequence to which polyclonal antibodies were raised includes:

CRQLEHDRATERKKEVDKF (SEQ ID No:16)

CFKHSSQASRSATPANSD (SEQ ID No:17)

RPEDESDLHSTPNADDQEC (SEQ ID No:18)

Glutathione S-transferase recombinant fusions with the ATM fragments from which polyclonals and monoclonals have been raised are set forth in SEQ ID Nos:19-23.

Antibodies raised against the ATM protein detect mono-specifically a high molecular weight of the expected size of 350 kDa on Western blots of protein lysates derived from fibroblast and lymphoblastoid cell lines. Because of the high frequency of truncation mutations in the ATM gene, mutated ATM protein can be identified if such proteins are stable. Indirect immunofluorescence showed the ATM protein to be predominantly nuclear. Cell-fractionation studies of normal fibroblast cells identified the presence of the ATM protein in both the nuclear and microsomal fractions.
